Kei te piki haere te whakamahinga o tētahi whakatupuranga hou o ngā silicone me ngā epoxies e ārai ana i te UV i roto i ngā mahi motuka me ngā mahi hiko.
He taupatupatu kei roto i ia mahi o te ao: Te whiwhi i tētahi painga i te utu mō tētahi atu, kia pai ai te whakatutuki i ngā hiahia o te āhuatanga e pā ana. Mēnā he nui te here, te hiri, te whakakī rānei i te haukoti, ka whakawhirinaki ngā kaihanga ki ngā piripiri UV-cure nā te mea ka taea te whakamaroke tere i runga i te tono (1 ki te 5 hēkona i muri i te pānga o te mārama).
Heoi, ko te rerekētanga, me whai papa mārama ēnei piripiri (kiririka, silicone me te epoxy) kia pai ai te piri, ā, he nui ake te utu i ngā piripiri e whakamarokehia ana mā ētahi atu huarahi. Heoi anō, he maha ngā kaihanga i roto i ngā ahumahi maha kua harikoa ki te mahi i tēnei whakawhitiwhiti mō ngā tekau tau. He maha atu ngā kamupene ka mahi pērā mō ngā rā kei te heke mai. Heoi, ko te rerekētanga, ka rite te tūponotanga o ngā miihini ki te whakamahi i te piripiri silicone, epoxy rānei UV-cure, ki tētahi e hangai ana ki te kiririka.
"Ahakoa kua hanga e mātou ngā silicone UV-cure mō ngā tau tekau kua pahure ake nei, i roto i ngā tau e toru kua pahure ake nei, me whakanui ake e mātou ā mātou mahi hoko kia mau tonu ai te hiahia o te mākete," te kī a Doug McKinzie, te tumuaki tuarua o ngā hua motuhake i Novagard Solutions. "Kua piki ake ā mātou hoko silicone UV-cure mā te 50 ōrau i ngā tau kua pahure ake nei. Mā tēnei ka whakaiti i ētahi, engari e tumanako tonu ana mātou ka pai te tipu mō ngā tau e whai ake nei."
Ko ētahi o ngā kaiwhakamahi nui rawa atu o ngā silicone whakaora-UV ko ngā OEM motuka, me ngā kaiwhakarato Tier 1 me Tier 2. Kotahi te kaiwhakarato Tier 2 e whakamahi ana i te hiri Loctite SI 5031 mai i Henkel Corp. ki ngā pito o roto i ngā whare mō ngā waeine whakahaere-pēra hiko me ngā pūoko pēhanga potae. Ka whakamahia hoki e te kamupene te Loctite SI 5039 hei hanga i tētahi gasket silicone kua whakamaroketia-UV ki te wāhi huri noa i ia waeine. E ai ki a Bill Brown, te kaiwhakahaere o te hangarau tono mō Henkel, kei roto i ngā hua e rua he tae kanapa hei āwhina i te manatoko i te aroaro o te piri i te wā tirotiro whakamutunga.
Kātahi ka tukuna tēnei huihuinga iti ki tētahi kaiwhakarato Taumata 1 e whakauru ana i ngā wāhanga ā-roto tāpiri, ā, e hono ana i tētahi PCB ki ngā pito. Ka whakatakotoria he taupoki ki runga i te gasket taha hei hanga i tētahi hiri ā-taiao mō te huihuinga whakamutunga.
He maha hoki ngā whakamahinga o ngā piripiri epoxy UV-cure mō ngā mahi motuka me ngā mahi hikohiko kaihoko. Ko tētahi take he mea hanga motuhake ēnei piripiri, pērā i ngā silicone, kia rite ki te roangaru o ngā pūtake rama LED (320 ki te 550 nanometer), kia whiwhi ai ngā kaihanga i ngā painga katoa o te rama LED, pērā i te roa o te ora, te iti o te wera me ngā whirihoranga ngāwari. Ko tētahi atu take he iti ake ngā utu whakapaipai o te UV-cure, ā, mā reira ka māmā ake te hokohoko a ngā kamupene ki tēnei hangarau.
